answer
(d) 61
Answer:
(x) = 
Step-by-step explanation:
let y = f(x) , then rearrange making x the subject
y = 6x + 7 ( subtract 7 from both sides )
y - 7 = 6x ( divide both sides by 6 )
= x
Change y back into terms of x with x =
(x) , then
(x) =

Answer:
Gain in total is $8.5
loss is $3.75
Step-by-step explanation:
His total load is 4*125 + 2*75 + 2*50, which is 750
now, is that 750 95% of 800?
well 95% of anything is 95/100 * anything
thus, 95% of 800 is 95/100 * 800 or 0.95 * 800
now, is that less than more or equals to 750? if it's, then he's golden, because his load is less or equals to 95% of 800, if not, then he needs to cut down some
